To all whom t may concern:

Be it known that ALEXANDER Mo- CREREY, a citizen of the'United States, residing at Hiawatha, in the county of Brown and State of Kansas, have invented certain new and useful improvements in Gage- Wheel-Adjusting Mechanism, of which the following is a specication.

This application is a division of an application led by me in the United States on the 25th day of May, 1915, Serial No.` 30,404 for motor driven plow and relates more particularly to the gage wheel mechanism whereby the gage wheel may be adjusted by diiferent means jointly or independently according to the result to be attained.

The invention is primarily designed yto provide means for adjusting the gage wheel or like part by hand and to combine therewith other means which are at all times under control of the operator to admit of instant adjustment of the gage wheel to raise or lower the plow or like part as may be found expedient to meet varying conditions in the operation of the implement or machine embodying the invention.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly claimed.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention as claimed may be resorted to when desired.

Referring to the drawings, Figure l is a perspective view ofa portion of the machine provided with the gage wheel and adjusting mechanism embodying the invention; Fig. 2 is a detail view of the pedal actuated means for adjusting the gage wheel; Fig. 3 is a detail view of the' operating lever and segment showing the latch connection between them.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

A portion of the main frame is illustrated and is designated by the numerals 1 and 14:, the latter being provided at its forward end with an arm 17 to the extremity of which is attached a vertical sleeve 27 in which is mounted a standard 28 provided at its lower end with a supporting and steering wheel 26, such standard being adjustable vertically in the sleeve 27 by means of a longitudinal beam 50 which constitutes a lever fulcrumed intermediate its ends and having its forward end connected by means of a link 5l with the upper end of the standard 28. The rear end of the beam or lever 5.0 is formed with lateral extensions adapted to engage the teeth 56 on the opposed face of a standard fixed to and rising from the main frame. A. shaft 57, parallel with the toothed standard 55, is provided with a vertically disposed eccentric or cam portion which is adapted to bear against the rear end of the beam 50 and press the same inwardly to bring the lateral projections thereon into engagement with the teeth 56 so as to hold the lever in an adjusted position. A spring` finger or like part 58 is secured at one end to the shaft 57 and its opposite end portion is inclined so as to engage a cam 59 which is oscillated by means of pedals 60 and 61 attached to opposite ends of a sleeve 62 mounted upon a transverse shaft 63. rihe movement of the sleeve 62 in one direction effects release of the nger so that the shaft 57 may be turned to release the lever 5() when it is required to move said lever in order to adjust the wheel 26 vertically. After the lever has been moved to the required position, movement of the sleeve 62 in the reverse direction brings the inclined face of the cam 59 against the inclined portion of the finger and swings the same inwardly, thereby turning the shaft 57 so that its eccentric portion will bear against the lever 50 and press it into engagement with the teeth of the standard 55. lThe lever will be held in this engagement with the standard until the pedals are actuated to swing the cam forwardly and thereby permit the inger to swing or be swung outwardly.

' ment of the gage wheel 101.

The gage wheel or like part 101 is mounted upon a lateral arm 102 disposed at the lower end 'of a vertical standard 103 which is mounted in a vertically disposed bearing sleeve 104 secured to a part of the main frame. The gage wheel 101 is adapted to have a caster movement so as to adapt itself to the direction of movement of the machine. A lever 105 fulcrumed upon a stud 106 projecting laterally from the main frame has its front end connected by means of a link 107 to a short bar 108 depending from a casting 109 fitted to the upper end of the standard 103. A link 110 connects the rear end of the lever 105 with an arm 111 projecting from a lever 112 which is provided with a latch `113 to engage a toothed segment 114 mounted upon a stud 115 projecting laterally from the main frame. A link 116 connectsv an arm 117 of the toothed segment 114 with an arm 118 of the cam 59 sov that movement of the pedals 60 and 61 will effect a corresponding vertical adjust- The gage wheel may be adjusted independently by means of the lever 112, which has pivotal connection with the toothed segment 114 at V11231. It will thus be understood that by holding the sleeve 62 in a given position and operating the lever 112 with the latch released from the segment the gage wheel 101 may be adjusted vertically without affecting the wheel 26. After the gage wheel has been adjusted to the required position it is made secure by the latch 113 engagingV the toothed segment 114. Rotation of the sleeve 62 forwardly or rearwardly by pressing upon the pedals 60 or 61 effects a lowering or a raising of the rear end of the lever 105 and a corresponding elevating or lowering of the gage wheel 101. When the operator is mounted upon the implement or machine the feet are placed upon the pedals 60 and 61, thereby admitting of the gage wheel being under control at all times and adapted to be moved vertically to meet existing conditions as may be required in the operation of the machine.

The lever 112 isV manipulated to set the gage wheel 101 so as to regulate the depth at which the plows will run, while the pedals arel manipulated to raise the gage wheel clear of the ground without shifting the gage lever 112 when it is desired to turn a corner and to replace the gage wheel in the former position as the turning of the corner is Vabout finished without requiring special attention from the operator. Downwardl and forward movement of the right pedal swings the cam 59 rearwardly and a slight rearward movement effects the locking of the beam or lever 50. The continued downward and forward movement of the right pedal swings the arm 118 forwardly and upwardly so that a pull isk exerted through the link 116 upon the arm 117 to oscillate the segment 114 and vibrate the lever 105 so as to lift the gage wheel, as will be readily understood. As before stated, the pedals or foot cranks are used in turning corners while the hand lever or gage wheel is used to regulate the depth at which the plows will run.

Having thus described the invention,what is claimed as new is 1. In combination, a main frame, a standard mounted upon the m-ain frame and` adapted to have a vertical movement imparted thereto and provided at its lower end with a crank aXle upon which a gage wheel is mounted, a lever mounted upon the main frame, a link connection between` the lever and standard, a toothed segment pivotally mounted on the main frame, an operating lever eccentrically pivoted upon the toothed segment and having connection with the first-mentioned lever, a latch mounted upon the operating lever and adapted to engage the toothed segment, and means mounted on the main frame eccentrically to and operatively connected with the segment for adjusting the same in its own plane.

3. In combination, a main frame, a vertically adjustable supporting member therefor, a lever fulcrumed intermediate its endsV upon the main frame and connected at its front end with the vertically adjustablesupporting member, a toothed segment pivotally mounted on the main frame in rear of said lever, an operating lever pivoted eccentrically upon the said segment and having connections with the rear end of the firstmentioned lever, a latch Acarried by the operating lever to lock the same to the segment for movement therewith, an arm depending from the segment, a rocking member mounted upon the main frame in rear of the segment, a link connecting said member with the arm depending from the segment, and means for actuating said rocking member.
